neo572,
I would go for the option 1 of Feriduni,I think because you have had strip surgery before and because you have all those zones to cover,combo will provide you more hair + you will likely save more donor for possible future procedure(s) than going for option 2 (full FUE).
between Feriduni & Bisanga,for a strip or strip+fue procedure I will choose Feriduni.
I'm also going for my next surgery (strip) with Feriduni soon.
Bisanga is also good,but for strip (or strip + fue combo) I like Feriduni better.
